Dear Qt Community,

I am drawing tiles/rectangles 8806using my custom QGraphicsItem (code below). I would like to add some style like QFrame:Panel Raised (attached image) on these tiles. Could you please suggest me how can I do this? Appreciate your help. Thanks.



void QGraphicsTileItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{

/// Draw the rect
painter->setRenderHints( QPainter::Antialiasing | QPainter::TextAntialiasing | QPainter::SmoothPixmapTransform | QPainter::HighQualityAntialiasing, true );
painter->setPen( pen );
painter->setBrush( colour );
painter->drawRect( bound );
painter->drawText( bound, Qt::AlignLeft | Qt::AlignTop | Qt::TextSingleLine, name );


}

See QStyle::drawPrimitive() with QStyle::PE_Frame

Sorry, I could not understand how to use QStyle here. May I request any of you to please write me few lines of code or a little bit of explanation. Thank you very much.

void Item::paint(...) {
QStyleOptionFrame opt;
fillWithData(opt);
QApplication::style()->drawPrimitive(QStyle::PE_Frame, opt, ...);
}

In doubt see how paintEvent for QFrame is implemented.

Sorry to bother you all. I am not getting what I am trying to. Actually my Qt code draws a treemap. Each rectangle of the treemap is a custom QGraphicsItem. I want to draw the boundaries of each rectangle in such a way which give a very mild 3D effect as shown in the attached sample treemap. I would like to draw the boundaries like this. Could you please help. Thanks.
